What problem does it solve? When new earnings, guidance, M&A, or regulatory events occur, analysts need to know which parts of an existing investment research report must be refreshed without rewriting everything from scratch. This Skill produces a structured update plan that scopes the re-execution work. ## Core Features & Use Cases - Impact Scoping: Compares the existing report's baseline date against the new event and identifies which workspace artifacts (input, valuation, macro/sentiment, risk scenarios, draft, QA) are affected. - Re-execution Planning: Lists the commands and skills to rerun in order, and flags whether the Rating and Price Target need revalidation. - Use Case: After a company reports quarterly earnings with a tariff-related guidance change, invoke this Skill to write an update plan to ${ACTIVE_WORKSPACE}/00_input/update-plan.md specifying that valuation, risk scenarios, and the draft must be regenerated while long-term sections remain unchanged. ## Quick Start Update the existing CSTM report for the latest earnings event and write the re-execution plan to the workspace update-plan file.
